Upgraded to ntopng 2.0 and get the error HTTPserver.cpp:486] ERROR: Unable to start HTTP server (IPv4) on ports 3000 about ntopng

[lucaderi]

Can you please move to version 2.3 and open a bug if the problem is still present?

[lucaderi]

@EdSchmidt Is the SSL certificate present in httpdocs/ssl?

[EdSchmidt]

In /usr/share/ntpng/httpdocs/ there is a ntopng-cert.pem file.

@EdSchmidt Please provide the complete command line you have used to start ntopng

[EdSchmidt]

I just moved the .pem file out of the ssl directory and everything works.

[lucaderi]

Well SSL won't work for sure.

@EdSchmidt how did you generate the pem file? Is it the same one you used with ntopng 1.99?

Apart from that being closed this problem is extremely hard to solve since the error messages are probably completely unrelated to the problem: there is error output without the matching syscall, so probably the output is bogus.

("[HTTPserver.cpp:495] ERROR: Unable to start HTTP server (IPv4) on ports 127.0.0.1;3301,127.0.0.1;3302s: Success" - no syscall to give "Success" or "Bad file descriptor" or other random nonsense.)

My PEM was the same as under v1.2.1 and it fails under v2.2. This is Debian/sid, and judging by the strace/ltrace everything is fine except SSL server doesn't work. Probably PEM file isn't what ntopng expects but the only solution is trial-and-error... (It's cat server.key server.crt > ntopng.pem right now.)
